Mitigations

Установка обновлений из доверенных источников. В связи со сложившейся обстановкой и введенными санкциями против Российской Федерации рекомендуется устанавливать обновления программного обеспечения только после оценки всех сопутствующих рисков. Компенсирующие меры: - настройка клиентов SSH на использование сильных ключей шифрования; - добавление только доверенных общественных ключей клиента SSH в ROS; - использование средств межсетевого экранирования для ограничения возможности удалённого доступа; - сегментирование сети для ограничения доступа к промышленному сегменту; - ограничение доступа из внешних сетей (Интернет); - использование виртуальных частных сетей для организации удаленного доступа (VPN).

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
